Application filed December 29, 1920. Serial No. 433,797.

To all whom it may concern.

Be it known that I, THOMAS L. TALIA- rnnno, a citizen of the United States, re-

v siding at Chicago, in the county of (look, State of Illinois, have'invented certain new and useful Improvements in J ar-Olosing Machines, of which the following is a description, reference being had to'the accompanying drawing and'to the figures of reference marked thereon.

The invention relates to new and useful improvements in jar closing machines, and more particularly to a machine for attaching a metal cap to a glass or porcelain jar.

An object of the invention is to provide a machine of the above character, wherein devices are provided for causing the jar to travel in a curved path and while it is mov-- ing to reshape the flange of the metal cap, 29 so as to secure it to the jar.

A further object of the invention is to provide a machine of the above character wherein the securing of the cap to the jar is brought about by means of a rotating vcurved memberwhich engages the flange at one side of the mouth of the jar, and a stationary cam ledge curved to conform to said curved member and spaced therefrom which engages the flange of the cap at the other side of the mouth of the ar, and wherein said rotatin member and said cam ledge are so dis se and constructed as to gradually turn t e edge of the flange of the cap underneath the shoulder or ledge at the mouth of the jar.

A still further object of the invention is to provide a machine of the above type, wherein the closin means for securing the metal cap to the g ass jar is so constructed 4 as to support and convey the jar by engagement with the flange of the cap and ledge at the mouth of the jar.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

In my copending application, Serial No.

433,796, filed of even date herewith, I have shown, described and claimed broadly a machine for securing metal caps to glass or porcelain jars, which includes a feeding means for the jar adapted to engage the flange of the cap and the flange at one side 7 of the mouth ofthe jar, whilea co-operating supporting ledge engages the flan e of the cap at the opposite sidelthereof an operates to reshape the flange of the cap so as to secure the same to the jar. ,The present invention is directed to a modified form of the type of machine shown, described and claimed in my said copending application.

In the present form of the invention there is a central rotating member 1, which, is circular in outline and consists of two disks 2 and 3. These disks are mounted on a vertical shaft 4. The shaft is mounted in suitable bearings 5 and 6 carried by the frame of the machine. I Said frame consists preferably of supports 7, to which is secured a table 8 by means of bolts 9-9. The shaft 4 is provided with a collar 10 which carries the lower circular member 3. The up per circular member is keyed to the shaft and rotates therewith but is free to move endwise on the shaft. A spring 11 encircling the shaft 4 bears against the upper member 2 and normally forces the same downwardly into yielding contact with the lower member 3. A wing nut 12 threaded on to the shaft serves as an abutment for the spring 11 and as ameans whereby the tension of the spring 11 may be varied.

- "Go-operating with the rotating member 1 is a curved cam 13. This cam is curved to conform in outline to the circular rotating member 1 and is spaced therefrom. Ex-

tending upwardly from the supporting table of the machine are three standards 14:, 15

ion

and 16. The curved cam 13 is carried by these standards. Each standard has a slot 17 and a clamping bolt 18 extending through the slot is threaded into the upper section 13 of the cam 13. This serves as a rigid means for securing the member 13 and permits the same to be adjusted vertically for difierent heights ot jars. The

lower member 13* of the curved cam 13 is ly into contact with the member 13*.

The shaft 41 carrying the circular member 1 is rotated by a suitable belt wheel 22. The cam 13 is curved or turned outwardly at 23, which is the. receiving end of the machine. It is also curved or bent outwardly at 2A, which is the delivery end of the machine. Between the receiving and delivering end of cam 13 there is a guiding plate 25. This guiding plate 25 is formed in two sections. The upper section 25". is rigidly secured to ,a cross bar 26, which in turn is rigidly secured by bolts 27-27 to the ends of the cam member .13. The lower member 25? is secured to ,the upper member 25 by means of bolts 28, which are threaded into the upper member and extend through openings in the lower member and springs 29 carried-by these bolts yieldingly force the lower member 25 upwardly into contact with the upper member 25. This member 25 is formed into two sections, as clearly shown in Figure 1, and each section is secured to the cross bar 26 by means of bolts 30;, which pass through suitable. slots in the cross bar and are threaded into the upper member 25*. The purpose of these slots is to permit the two sections to be adjusted toward or from the ends of the cam 13 for changing the width of the space between these sections and the ends of said cam member.

Travelling in front of the machine 'is an endless belt 31 which runs over rollers 3232, mounted on bracket arms 33 respectively. Extending over this endless conveyor and in part over the table 8 is a disk 34. Said disk 34 is rigidly carried by a shaft 35, mounted in a bearing 36 in the table 8, and the shaft 35 is driven by a'suitable belt wheel 37. This disk is very thin and is provided with a knife edge. The jars on the conveyor 31, moving in the direction of the arrow in Figure 1, will be delivered on to the rotating disk. The disk rotating in the direction of the arrow shown in Figure 1 will carry the jars against the guiding arm 38 and into the space between esca ees the guiding member 25 and the end of the cam ledge 13. The member 25% clearly shown in Figure d. is formed with a recess 39, while the member 25 is formed with a recess 440 The member 13 is formed with .jars before they enter the machine. The

disk 34 rotating causes the jar to travel along the space between the cam ledge 13 and the guiding member 25., and when the point {l is reached, the llange of the cap will come into contact with the rotating member 1. This rotating member 1 as clearly shown in igure 3, is provided with a recess d5. This recess 15 is formed in part in the member 2 and in part in the member 3 and is in alinement with the recesses formed in the guiding member The upper and lower walls of the recesses 41 and 42, respectively gradually approach each other, as will be apparent from Figure 5, wherein the section is taken onthe line 5-5 of Figure 1, and it will be noted that the upper and lower walls of the recesses 11 and 412 are much closer together at this of the jar and the cap will be presented to the cam ledge. As the recess in the cam ledge grows narrow, the lower portion of the flange of the cap will be gradually- .tucked underneath the shoulder 43 at the mouth of the jar until the cap is finally drawn down tight on to the jar and the flange tullv turned underneath the ledge, as clearly shown in Figure 5. llnasmuch as the jar is supported during the closing of the same, there is no pressure upon the body of the jar. The upper part of the rotating member 1 is yieldingly pressed downwardly by the spring 11 and, therelore. these parts will yield to prevent the breaking of the jar mouth, but the pressure is sulhcient to aid in the rotating of the jar and in the folding oil the metal underneath the shoulder on the jar. Likewise, the

lower part of the curved cam 13 may yield, so as not to crush the mouth of the ar, but thesprings are of suflicient tension to cause the gradual turning of the metal of the flange underneath the shoulder on the jar.

From the above it will be apparent that l have provided a machine wherein the jars travel continuously in a curved path, and may follow on upon the other without any special timing, whichis quite an essential feature in this type of machine. These jars are supported by the ledge at the mouth of the 'ar during the closing operation and as the ]&I' travels it is rotated so as to bring the flange of the cap at all parts thereof into contact with the cam led e and this cam ledge radually tucks the ower portion of the flange underneath the shoulder at the mouth of the bottle. After the caps have been secured to the jar they are again delivered on to the rotating disk 34 and carried out through the guiding passage between the member 25 and the end 24 of the cam ledge 13. The jars engage'a guiding arm 50 and are directed ofl from the disk 34 on to 'the endless conveyor 31, so that the endless conveyor brings the jars to the machine and I carries the closed jars away from the machine. This guiding arm 50 is formed with a shank 51 and'is secured by bolts 52 to the supporting member 25. The lower member 25 of the supporting member 25 is provided with a slot and also-with a recess, as clearly shown in dotted lines in Fig. 2 of the drawings. The heads of the bolts 52 are sunk in the recesses and the bolts extend through the shank 51 of the arm 50 and thus it is that the shank is bolted to the lower member 25*, so that the members 25 and 25 'can yield one relative to the other. By loosenin the bolts 52 the guiding arm can be shifte one way or the other, as desired. 1

While I have described and shown in Figures 4 and 5 a jar closure wherein the cap is,

bent underneath a shoulder on the jar, it will be obvious that my machine, by changing the form of the recesses in the rotating member 11. and in the curved cam ledge 13, readily adapts itself for use in closing other types of jars. For example, in Figures 6 1 and 7, l have shown a jar 47 having a substantially straight outer wall.- The cap 48 is provided with a flan e formed with a pocket in which is placed a sealing ring or gasket d9. The sealing of the jar is brought about by chan ing the shape of the pocket in the metal ange containing the rubber sealing rim or gasket. In this form of the invention t e jar is supported by the table. It will, however, be rotated by the rotating member 1 and the cam ledge 13 has its recess shaped so as to gradually reshape the flange and force the gasket into gripping contact with the side wall of the jar. Here too, the members on the rotating member 1 and the cam ledge 13" may yield to prevent the crushing of the jar which at the same time will bring about the proper reshaping of the flange to-bring about a proper sea It will be obvious, of course, that my improved closing means may be readily adapted for closing in vacuum.

It will be obvious that minor changes in the details of construction and arrangement of parts may be made without departing from the spirit of the invention as set forth in the appended claims.

Having thus described my invention, what 1 claim as new and desire to secure by Letters Patent is:
